Which statement by a mother indicates a need for further teaching regarding dental care for her 2-year-old?

The statement indicating a need for further teaching about dental care for a 2-year-old is that proper dental care is not necessary for toddlers until their permanent teeth erupt. This idea is incorrect because dental care should begin as soon as a child's first teeth appear, which typically occurs around six months of age. Maintaining good oral hygiene in early childhood is vital to prevent early childhood cavities and other dental issues, which can arise even in primary teeth.

Regular brushing with fluoride toothpaste, as mentioned in other choices, is recommended to protect against decay. Additionally, scheduling regular dental visits is essential for monitoring the child's oral health and addressing any potential problems early. Avoiding sugary snacks reinforces good dietary habits that further protect dental health. Hence, a statement dismissing the importance of dental care until the eruption of permanent teeth indicates a significant gap in understanding proper dental hygiene for young children.
